Warm-up 2: What is a lethal allele? What is an example of a lethal trait in humans?
1. Correct assignments
2. Notes: Complex inheritance
3. Practice: Epistasis and Blood types
1. Go over dihybrid crosses
2. Review for test
STUDY FOR TEST TOMORROW
No warm-up- study for quiz
1. Opener- quiz
2. Work session- human traits analysis and human genetic disorders
3. Closing- dihybrid cross practice
Warm-up 4: Draw the pedigree for hitchhikers thumb (a recessive trait) in the family described below.
In generation I, Joe who does not have hitchhikers thumb marries Mary who has a hitchhikers thumb.
They have 3 children- Mike, Jane, and Jill. Mike and Jill have hitchhiker's thumb.
Mike marries Susan (no hitchhikers thumb) they have 2 sons without hitchhikers thumb.
Jane marries Bob (hitchhikers thumb) they have a daughter with hitchhikers thumb, one son with hitchhikers thumb and one son without.
Jill marries Andy (no hitchhikers thumb) they have two daughters- one with hitchhikers thumb and one without.
1. Opener- correct pedigrees
2. Work session- Dihybrid cross notes
3. Closing- complete pedigrees and dihybrid crosses.
HW- study for quiz tomorrow (pedigrees and punnett squares)
Warm- up 3: Show the cross between a homozygous dominant individual and a heterozygous individual. What percentage of their offspring will express the recessive trait? Use A's for your letters.
